What should you look for during a visual exam of a tire before rotation?

In a visual exam of a tire before rotation, it is crucial to identify any structural or safety issues that may affect the performance and safety of the vehicle. Observing for bulges, cracks, nails, or excessive wear is essential because these conditions can indicate potential tire failure, which could lead to dangerous driving situations.

Bulges in the tire might suggest that there is internal damage, often due to impact or over-inflation. Cracks can occur from age or wear and may compromise the tire's integrity. Nails and other foreign objects can puncture the tire, leading to air loss and potentially becoming worse if not addressed. Excessive wear patterns can indicate issues with alignment or suspension and may require corrective actions.

Other options focus on aspects that, while relevant, do not directly correlate to the immediate safety and functionality of the tire in the same way. Therefore, the identification of physical deformities and wear in the casing and tread is a critical part of ensuring that the tire is in safe working condition prior to rotation.
